Sensor-Crankshaft Position: Description

The crankshaft position sensor is located at the left rear of the engine just above the starter motor. The sensor detects the crankshaft position contactlessly (hall effect) by means of missing segments on the tone wheel behind flex plate. The electronic control module (ECM) detects TDC position of cylinder 1 by means of the signal supplied by the sensor. Injection timing is synchronized by means of the camshaft signal and the crankshaft signal. This sensor is used to detect engine speed.
